While there may be some element of truth in this, there is a more basic reason; the total number of Tiptronic cars is a very small fraction of the total number of the Boxster fleet. As the result, few Tips fail simply because there are fewer of them to begin with. But they do fail.

Interestingly, there are more than just one or two single owner, multiple IMS failure reports; so driving style may play into what factors lead to the problem; but again, only one source has most if not all of the data, and they ain't talking.....
